Applicationv filed February 9, 1909. Serial No. 476,970.

an incinerator of simple, inexpensive construction and one which will be ecoi'iornical ot' operation and easily handled.

further object is to provide an apparatusI that is capable of application to crema- 1`5 tories which are already installed and in operation.

A further object is to provide an incinerator having;v a gas consuming chamber in which the. products of combustion and the gases arising from the materialy will be consumed before entering the stack.

.A further object of our invention is to provide means in the. combustion chamber forv dividing or separating the material to he consumed to facilitate its combustion,

preventing the packing together of wet material, which will sometimes occur where only one grate is employed, the upper suspended grate being so constructed that the.

material thereon can he discharged upon the lower or statitniary grate at, any time.

()nr invention consists generally in a hangingl or suspended `grate, which ycan be used or not, as desired.

Further` the invention consists in 'providing headers above said suspended grate whereon a portion of the material to he consinned may be supported.

I "urther, the invention consists in provid- 40 ing a grate and combustion chalutier adapted to receive inflan'nnahle material such paper.

Further, thc invention consists in circulating tubes to pci-mit the heat of the lu'rir ing material to be utilized-to generate steam for coum'iercial purposes. I

Further, the invention consists in a gas consuming furnace having a hopper leading to the dumping Hoor, by means of which we are enabled to use combustible material on tory.

Further, the invention consists in various constructions and combinations all as heren inaftcr described and pointed out in the f claims.

part of this specification, Figure 1, a longitudinal, vertical, sectional view et an inoinerat-or embodying our invention, 2, is a transverse, vertical, sectional View of the same on theline X---X of Fig. l.

In the drawing, 2 represents a brick cas ing or setting having a roadway 3 thereon, provided With-a series of filling openings 4 normally cloped by covers 5. These covers are preferably1 composed of a combination of .metal and concrete, as shown. Below these covers are feed spouts 6 leading to a Vcornbustion chamber 7. We have shown three of these filling openings in the roadway, but the number may be increased or decreased according to the capacity ofthe incinerator. In the bottom of the combustion chamber we provide a series of gratas 8, having ash pits 9, which are accessible through doors 10. Openings 11 and 12 are provided in the wall of the casing through which access may be had to the space above the gratas 8 ,and the combustion chamber 7. It often happens in an apparatus of this kind, that the material is wet and soggy and when thrown into the combustion chamber, will pack down around the grate and prevent the fire from working through the mass and igniting the combustible material.V To obviatei this ditiieulty, we provide a suspended or hanging grate consisting of a series of tubes 13, connected at. their upper ends toga pipe 14, and having inwardly turned lower ends which are con- ,nectcd to a pipe 1.5, which extends from' end to end ot' the combustion chamber.' Pipes -16 are attached to the ends of the pipe 15 and project up through the crown of the combustion chamber and are connected with pipes 14. These. pipes 14 are capable. of oscillation in their supports to allow the sections of the hanging grate to move back and forth toward or from one another' to close the s )ace 'between the sections and support the iiiatcrial deposited thereon or allow the niatcrial to drop through upon the stationary gratos S beneath. le prefer to provide suspended sections with inwardlyv and down wai-illy curved tower portions so that the material carried by the basket sections will tend to work toward the center of the cham- In the accompanying drawings, forming' chamber.

ber and toward the space between the sections. This movement ot' the material will be facilitated when the sections Vare swung apart` to widen the discharge openingr between them and allowI the material to fall upon the stationary grate beneath. The pipes 16, provided at the ends ot' the seo tions are, as shown in Fig. 2, inclined to form guides to direct the material contacting therewith toward the middle portion of the This construction prcver'its the material from packing down in the basket and greatly facilitates the handling of the load on the grate. These hanging grate sections are oscillatcd by any suitable means as by bars 17 having teeth 18 adapted to engageplates 19 and lock the grate sections' i'n any desired angle in the'combustion chamber. The space below the hanging grate is divided transversely by walls 19', having plates 19 on which the lower ends ot' the The pipes composing the hanging grate are thus supported when the grate is loaded. Walls 19' having a further function of dividing the lower stationary grate into a series of sections so that one or more fires may be -maintained on the grate, and one can be stirred, if necessary, without disturbing the res on the other sections of the grate. The combustion chamber has a series of flues- 20 leading' therefrom `to a descending fine 2l,

- which has a horizontal extension 22 communicating with thefstaclc 23. A horizontal flue 21 leads from the space below the hang.- ing grate to' the descending tine l2l, and is provided with a Vvalve 21"' by means of which the passage of the products of combustion-through the tlue may be regulated. By means of this flue we are able to conduct.

the gases and products of combustion from' the paper consuming chamber through the main combustion chamber of the incinerator to the stack without, passing the products of combustion into the gas consuming chamber. The tlues 20 extend through a baille wall 2'` provided at the rear of the con'ibustion chamber and separating it. from the descending flue 21. Abovef the. lower portion of the hanging grate we provide headers consisting of horizontal'pipes 24 arranged on each side of the combustion chamber and provided with longitudinal partitions 25, which divide their interior into chambers 26 and 27. A series of pipes 2S communicate with the chambers 27 anda. series of smaller pipes 29 are arranged within the pipes 28 and communicate with the chambers 26. iVl'ien, therefore, water enters the chambers T and flows down into the pipes 28, it must enter the pipes 2t) and flow therethrough before entering the chambers 2G. The pipes 28 and 29 project laterally liron the. pipes 24+. into the combustion chamber and are raised or lowered by the oscillation of the pipes 24 i a series oit circulating pipes 3*) The` and this oscillation takes place by any suitable means, as the shafts 30, having operating wheels 3l and suitably connected with the pipes 2.4J By this means, the pipes 2S and 29 may beswung down to an inclined inoperative position or raised to a ljiorizontal position, where they will cooperate with one another toformyanother grate upon which the material from the spouts will beldeposited. W ith this apl'iaratus, we are able to divide material delivered to the incinerator, a portion falling on the stationary grate 8, in the bottom of thecombustion chamber,-

a portion being supported by the oscillating suspended grate' above and a third portion being caught and held by the headers in the upper portion of the'combustion* chamber. By dividing lthe material inlthis Way into separate masses, we increasethe surface eX- posed to the action of combustion and prevent the material from packing and becoming so firmly embedded in the bottom of the combustion chamber, as to prevent the flames from working through the mass andI When l tion chamber, the opposite pipes of the saine pair beingfconnected by cross pipes-53,

.through which'-y the water supply may be introducedfiti preferred.' A steam drum Bftis mounted on the upper wall ofthe combustion chamber above the lue 21 and connected with the circulatingr pipes an'd from this drum, steam may be drawn for commercial or power purposes. The combustion chamber has a crown wail 35; provided with a series of openings 3G in which the pipes oi the suspended grate are adapted to oscillate and also provided with holes f5?, through which the gases from the material beneath and from the products of combustion may pass into a gas consuming chan-r ber 38 that is formed between the crown wall 35 and the top of the incinerator and extends around the lining 3f) of the spouts through which the material is discharged into the'eomlnistion chamber. The walls ot this combustion chamber are composed ot lire l), k, which beate to a high tcmperature and has the elect. of igniting the gast-,s therein and etlecting their comenstion and consumption, before reaching the liuc 2l, which leads into the stack. At the rear of the combustion chamber we provide cenununiroo -to materially increase the ciiculating surface for -the enerati'on of steam. v At one -si e of the roadway is a filling opening 40 having a cover 41, corresponding to those heretofore described and leading'to a combustion chamber-42. in the bottoni of which is a stationary grate 43 and` a water grate 44, so called because it is'composed of tubing and connects with the circulating pipes, heretofore described. This combustion'v chamber connects with the chamber 7 through a passage 45 andiwhen desired, thevalve 46 i's adjusted so that the ttames and produetso combustion-will be drawn down through the grate 44, for the.

purpose of heating the water therein and increasing the suppl of steam to the drum 34` This combustion chamber 42 .is 'designed particularly tdreoeive such waste material as paper and-ether garbage, of a combustible nature andthe i iition ot this material iinv this chamber wil have the ef fectof heating `Vthe, walls the lgas consuming chamber, so thatevomhustiion and consumption cf the gases wi 'ke place 'theref in h'efoi'e'the material in `theg'chamber 7 has become sutticiently ignited-"to heats the walls of the 'gas,consuming"`ch`mber.

We also provide ascombustion chamber 47 having a filling opening-4 8 and gratos 4t) andO vzirranged one above another -aud communicating through atiue 5l with the gas consuming chamber. The grate 50 is connected with vthe circulating pipes and combustible material is placed on the grates 49 and 50 for 4the purpose lof effecting a preliminary heating o f the walls of the gas consuming chamber. This combustion chamber 47`has a valve 52 through which communication may be had with the chamber 42 and this valve may be opened to allow the sm'olte a-iid products of combustion from the chamber 4f). to pass through into the flue 51 and the gas consuming chamber. ".lhis valve will'lie opened wheirthe'material is burning', in the chamber /t'aiid it is dcsii'ed to charge the. chamber again andV e rept' for this Valve the smoke and products of coinlnistion would escapefi'om the combustion'chambcr. The heating of thc ualts ot' thc gas consuming chamber also has the ctt'ect of creatingr a drat't and hastcning thtl combustion of the material on the grates.

The gi'ates'44 and 5() are constructed on the header principle, illustrated in Fig. 2, there being a longitudinally divided pipe atV one side of the grate fromy the chambers of which horizontal pipes radiate and are arranged within one another, as indicated in Fig. 2.

By suspending a hanging grate above theA crown in the gas consuming chamber, we

are able toA apply this attachment to crema-v tories, which are already in use. Some crematories are constructed with 'crowns so low that there would be no room for susi x pendingthe hanging grate.belo\\',the crown, 75

The use of this hanging grate enables us to` utilize the heat from the lowergrate to f burn the suspended material rand the auxiliarygas consuming furnace is heated tol a high degree of temperature by thc ilames from t-lie burning suspended material and,`

the gases and products of combustion pass- 'ing through the superheated gas consuining` furnace will be entirely consumed before.y reaching :the stack. .,'lhrough .the feed spout 85 or hopper of the gas consuming furnace,

combustible material can be delivered to `t-he down draftV grate, rendering it unnecessary to burn a commercial fuel on thisgrate `when there is suticient combustible material 9G in the arbage. A considerable saving is thuse ected in the cost of operatingthe plu-nt. By locating the g'as consuming `fur.u

nace above and in front ofthesusp'ended y grate,. it is only. necessary to. burnasma-ll v amount of material toobtaiii `a high degree of temperature in the furnace sutiicient tov destroy all noxious odors ,before they4 can c reach thestack. lVe prefer to buildy agas consuming chamber of tire bricl{which will absorb and retain the heat and1bytrprovidiiig a series of openings in the crown wall of the combustion chamber, the gases will be divided and coming in contact with the refractory material forming the wall of the chamber, will he more rapidly and fully consumed.
